I haven't tested any recent versions, but the original development was near mostly done with Simics and it did work well for me. iirc there was a recent bug that the optimized memcpy or memset in the glibc didn't like a CPU returning 0 bytes of cache size and Simics did that. You might have run into that. It should be fixed now. Bochs used to be quite buggy on the x86-64 department and didn't do multi processor, but that also might have changed. It is significantly slower than the others. > > Even if I can't trace the kernel, is there anything available for just the > user space stuff? The AMD CodeAnalyst for Linux has a simulator that first collects a trace and then runs that in a CPU model. I assume it does first single stepping. It's unfortunately binary only. If slow single stepping is enough it's reasonably easy to write something yourself too. I have old example source that implements single stepping. However I doubt any of them are capable of running the bigger benchmarks. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
